Improvement in granulating sugar



UNITED STATES PATENT QFFIGE.

JAMES A. MORRELL, OF NEW YORK, N. Y., ASSIGNOR TO HIMSELF, JAMES H.WHEATLEY, L. P. WILLIAMS, AND GEORGE H. BAXTER, OF SAME PLACE.

IMPROVEMENT IN GRANULATING SUGAR.

Specification forming part of Letters Patent No. 142,498, datedSeptember 2, 1873; application filed I July 18, 1873.

To all whom it may concern:

Be it known that I, JAMES A. MORRELL, of New York, in the State of NewYork, have invented an Improvement in the Art of Granulatin g Sugar, ofwhich the following is a specification:

0n the 12th day of September, A. D 1871, I took out Letters Patent ofthe United States for an'improved process of manufacturing,

' into the vat, vessel, or caldron in which granulation is induced, of acurrent or currents of induced electricity, the effect of which seems tobe to prevent the suspension of granules of sugar, or particles subjectto granulation, by the glucose contained in the sirup, andconsequentlyin an increased production of sugar.

To enable persons skilled in the art to operate my improvement in theart of manufacturing sugar, I will proceed to describe one form ofapparatus in which my improvement may be worked; but my claim hereinwill not be limited to this form of apparatus, since it is manifest thatthe process is .not dependent upon any special form of apparatus, eitherfor reducing the sugar or inducing the electrical currents, for thesemay be almost indefinitely varied without departing from the principleof my invention.

The sirup being contained in suitable vats,

vessels, pans, or caldrons, an electrical machine for evolvingfrictional or common electricity, conveniently placed, is then to beoperated by any convenient power, and insulated wires, connected withthe respective poles, are then to be lead into the sirup, and electricalcurrents through the sirups thus evolved.

Whatever may be the physical causes of crystallization, I believe myselfto have been the first to employ, externally and artificially, inducedcurrents of electricity, of any of the known varieties, as an element inthe manufacture of sugar; and these currents need not be of frictionalelectricity, for other forms of electricity will produce the sameefl'ect; and though I have described a machine for evolving frictionalelectricity as a part of the described apparatus, I do not desire tohave it understood that my process is limited to that form ofelectricity.

What I claim as my invention and improvement in the art of manufacturingsugar is The introduction'into the mass of sirup undergoing granulationof an induced current or currents of electricity, such induced currentnot entering with a current of air, as covered by my Letters Patent ofSeptember 12, A. D. 1871.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. V
